Calgary rivers

Authentic Alberta stream geometry. Animation follows each mapped segment; no downstream topology has been verified.

Prototype. Water badges show a number only where a live rivers.alberta.ca reading exists (provisional, Alberta Environment and Protected Areas); other spots show no number. No observed current speed or swimming-safety data.

What this demo establishes

Moving particles follow real, attributed polyline bends. Coordinate-order animation is explicitly illustrative. Disconnected lines are never joined. Verified-direction mode suppresses all motion until a direction record is supplied.

Drag or use arrow keys to pan; + / − to zoom. Motion pauses during map gestures, while hidden, and for reduced-motion preferences. Streets stay disabled under the provider hold. Satellite mode uses Mapbox Satellite tiles on the hosted preview.

Thermal circles are withheld because the recovered V12 circles were not clipped to water. No heat distribution is invented here.
